Several inches of snow expected for Pittsburgh region

The winter storm expected to blanket much of Southwestern Pennsylvania with 4 to 6 inches of snow was downgraded Sunday to 1 to 3 inches of snow during the day and an additional 1 to 2 inches between midnight and 2 a.m. Monday, the National Weather Service in Moon said Sunday morning.

The snow is starting to fall in Moon Township, in the western end of Allegheny County, and should hit the rest of Southwestern Pennsylvania within an hour, Myranda Fullerton, National Weather Service meteorologist in Pittsburgh, said at 11:15 a.m. Light snow reached the Greensburg area at about 12:15 p.m. and by 5 p.m., roads in the Greensburg area were layered with slush and some snow-covered.

With the storm moving farther south, the weather service downgraded its winter storm warning to a winter weather advisory for much of Southwestern Pennsylvania. The advisory, which took effect at 10 a.m. Sunday, continues through 1 a.m. Monday. The advisory covers Allegheny, Westmoreland, Washington, Fayette, Green and Indiana counties in Pennsylvania as well as several counties in West Virginia.
